I say the demoman for the fact that it is the only class that can kill someone without even knowing that the person was there. The soldier can spam too, but he has to see where the rocket is gonna go. If he shoots and someone walks in front of the rocket, it's lucky hit, but he WAS aiming somewhere. The demo can shoot at places he doesn't even know where someone is and get a kill and say: nice, I didn't know someone was there.
At least the stickies let the demo time when he wants to explode them, so he can wait for someone to get on them. But then again, once, as a spy on warpath, I was cloaked and way behind the ennemy who had moved forward before I had the time to follow them. There was an unuseful sticky field and I tought: I'm cloaked and there is absolutely no risk of an allied to come by so the demo blows then and gets us both. I walked on them and at the same time, the demo, 3 miles away not even looking at them, blew them all so he could place them somewhere else. I was really angry that time.
My phrase is: deserve your kill. Work for it, aim and get it, then you are good. I don't care getting pwned 300 times by any class that aims at me, but if I get killed even once by a demo that didn't even know I was there, I say he's overpowered.

The trade-off, though, is that he is completely useless against someone standing right in front of him. Sure, you could get lucky firing a grenade, but they don't go where you point them anyway.
At mid-range, the demoman takes insane skill to be good at. Think about it. Sniper has only to point his dot and fire, soldier point and fire, scout point and fire, etc etc. But demoman's bombs don't go where you point. You have to calculate to account for the bizarre trajectory of your grenades as well as the slow speed of your projectile.
If you can hit people who are moving with a bullet that may take well over a second to arrive and travels in a crazy arc, I say that's skilled. Not to mention that bullet can't even kill a scout with a direct hit unless you crit.
And about killing people you can't see, the real skill for demoman is purposely positioning yourself where you are less vulnerable and delivering damage to an opponent who really can't see or hit you...kind of like...oh...idunno... A SNIPER!??!!
